Sun, 17 May 2015 20:03:27 -0700 Michael Pavone Make sure z80_save_reg does nothing when there is no register in the reg field of the instruction. This fixes a bug that corrupted SP in the MDEM 2011 demo

Sun, 17 May 2015 15:41:15 -0700 Michael Pavone Don't overwrite an instruction offset mapping with an extension word value. I really need the ability for a word to be mapped to more than one instruction, but this will be more correct for now
